I’m having a strange global scoping situation.
I’ve defined an action hook function that’s called from my plug-in. I’ve verified the hook is getting called as is the action hook function itself. But although I’ve specified some WP globals inside that action function (like $pages, $post, etc — along with some basic string globals) with the global statement, when I modify the globals inside my function, they don’t change in the WP/PHP global scope.
However, if I use the GLOBALS super-global, and I do something like set $GLOBALS = bar, then the global gets updated in the global scope.
I’m assuming I’m doing something wrong because I’ve never seen other actions use lots of super-globals, but I can’t seem to get the settings inside the function to go outside. And, just to make sure it’s clear, I am declaring the variables that should be global as global inside my action function.
Any advice would be much appreciated.
